I tend to mostly drink socially.
I will only drink at home if we have something I like. If there's a good bottle of red wine it generally won't last the night. I also love a drop of single malt or honey jack but I would never drink a whole bottle, maybe a couple doubles a night till its gone. Being German, beer needs to be of good, generally German/Belgian/Dutch/French quality. I can happily go without alcohol for weeks at a time.
I also find I drink different drinks depending on the time of year. In warmer weather I prefer an ice cold beer/ale or a good sweet cider such as thatchers. Red wine and whisky is definitely more of a winter warmer for me.
